L76 or Crow 105s for 1.95 roller rockers?



Yea I might be fine... but I rather play it safe.

I think I read somewhere that stock springs are good for up to ~ .470" lift (could be wrong though)
Sure these engine components are over-engineered most of the time... but I'd rather not push my luck.
 
Lift wise stock springs will never bind on stock retainers.

Floating will never cause damage just leaves the potential for horsepower loss at high rpms... and reving extra on those rockers wont even gai. You anything either way.

Depending on how the valve floats, you can cause serious damage immediately.

You need to float the valve a solid 30 degrees or more at full lift to cause piston impact. These are not hemi heads nor are they anywhere near hitting the piston. You will lose enough power that by the time you are floating bad enough to get 10% of the way to the piston, the motor will just not run.

I agree with everything you said here, besides the bolded portion. I just wanted to let him know that valve float can cause immediate damage....not just unusual wear, etc...

What about binding on stock springs with high ratio rockers?

And you have tested this? Or are you just another drive by poster?

ive got hs1.9's and floated like a bit*h at 5500 buddy... now i need a new engine because when you float an intake valve the explosion happening in ur cylinder isnt being contained to the cylinder it is also blowing up ur intake manifold:)
 
seperated lim from charger and warped them both just enough to where no amount of gaskets or sealers will fix the giant vacuum leak:(
 
said engine also has 258k and has had the holy shi*t beat out of it but made me lots of money found a 110k replacement for 350:)
 


Lol @ combustion happening in the intake manifold. Now THAT insures complete combustion of the air and fuel. Shouldn't you make more power then? :Cartroll:
 
I've just been lurking. I don't really post much in forums during winter. It's good to know that I was missed, I felt the same way about the forum. <3
